Avalane of the Flying Cactus"Why, by the white of Merlin's beard, did you use a cactus?" Kalliope shouted as she bounded down the stairs, three by three."It seemed like a good idea at the time!" Avalane called from somewhere behind her.They were in hot pursuit of a flying cactus. The potted desert plant soared through the corridors, flapping its thick, spiny, branch arms as it screeched "CHEESE" at the top of whatever it used for lungs. Along the way, it dropped toasted bread crumbs and melted cheese off its spines.According to Avalane, she had been trying to transfigure a cactus into a grilled cheese sandwich, but something went horribly wrong."What spell did you use?! Neither grilled cheese sandwiches nor cacti have any kind of bird characteristics." Kalliope skidded into an abrupt about face as the reckless plant/bird turned a sharp corner and made a break for the courtyard."I can't remember... it seems to be fairing pretty well with those arms," Avalane panted."I think... by this point... they're wings.
